Unique-technology High Strength Repair Wrap is made of high density fabric and coated with water-activated polyurethane resin. Quick and simple to use with no mixing or measuring required. A successful pipe repair can be achieved in only 30 minutes.It uses environmental friendly materials, and mainly used for Repair Oil , Gas & Water Pipeline etc,and adheres to Metal, plaster, PVC, Copper, Rubber, Fiberglass, Concrete, Wood, Ceramic, Polyester, etc.It can be applied on cracked, fractured, corroded, damaged & leakiing pipes, can also be used around different shapes including straight lengths,tee and elbow joints.It is suitable for using on wet or dry pipes. It can even be applied underwater, in fresh or saltwater.
You can see clearly that our tape have more resin and density of fabric is better than the normal fiberglass wrap on China market. That will make it withstand over 18Mpa strength if used together with epoxy putty.

Direction for Use
◆ Clean and roughen the damaged area with the metal file or wire brush, which will help resulting a more succesful repair.
◆ Put gloves on,open the bag and immerse the bandage in temperate water for 10-15 seconds & squeeze the wrap to let the water soak in evenly.
◆ Squeeze out the access water, apply the wrap spirally around the damaged pipe area. Extending up to 50mm(2″)either side of the leaked area.
◆ When wrapping, put each layer tightly and firmly, using hand to mould and squeeze the layers together in a tightening motion. Continue to apply pressure during application and upon completion.
◆ Suggestion: To achieve the best result,the wrap should be more than 10mm thick (10-15 layers). Allow 30 minutes for wrap to set rock-hard.
